Recombinant Human IL-22

Product Details

Catalogue Number: 200-22
Description:

IL-22 is a member of the IL-10 family of regulatory cytokines, which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26.  Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions.  Produced by T lymphocytes, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the liver and pancreas.  IL-22 signals through a receptor system consisting of IL-10Rβ/CRF2-4 and IL-22R, both of which are members of the class II cytokine-receptor family.  Recombinant Human IL-22 is a 33.6 kDa, non-disulfide-linked, homodimeric protein consisting of two 147 amino acid polypeptide chains.
